Write a function in C++ to count number of uppercase alphabets prsent in a text file ARTICLE.TXT.

Given the following class:
char *msg[]={:overflow"."underflow"};
class stack
{
  int top;//the stack pointer
  int stk[5];//the elements
  void err_rep(int e_num)
  {
    cout<   }
        //report error message
  public:
     void init(){top=0;}
        //initialise the stack pointer
     void push(int);
        //put new value in stack
     void pop();
        //get the pop value
};
Define pop outside the stack.In your definition take care of underflow condition. Function pop should invoke error_rep to report underflow
